ROOFING MATERIAL.

Specification of Letters Patent.

Patented oet. i9, 1915.

Application led January 28, 1914. Serial No. 815,058.

To 4all whom 'it may concern.'

Be it known that we, ALEXANDER S. SrininL and LOWELL F. LINDLEY, citizens of the United States, residing at Chicago, Illinois, have invented certain new and useful Improvements in Roofing Material, of which the following is a speciication.

This invention relates to prepared roofing and particularly shingles made therefrom. As at present made shingles of this character are cut from the prepared material which is built up of several layers consisting of a base of felt covered with a composition coating upon which, while plastic, is sprinkled sand or grit. When the shingle is laid only about four inches of it is exposed to the weather as the remainder thereof is covered by the next row, etc.

Now the particular object of this invention is to provide a way of covering the felt base of the shingle with a coating and sand only where it will be exposed to the weather.

With this and other objects in view the invention consists in the constructionand arrangement of parts hereinafter described and more particularly pointed out in the claims, it being understood that we 'do not wish to limit ourselves to the details of our invention.

lVe have illustrated Aour invention in the accompanying drawings in which- Figure 1 shows a side elevation of the machine for coating the roofing in the present manner. Fig. 1a showsy a modification of the coating thickness regulator. Fig. 2

-` shows a sectional view with one of our Fig. 3 shows a sectional coating machine with four Fig. 4 shows the material coated according to this invention and from which shingles may be cut. Fig. 5 shows a special form of roofing coated according to this invention. Fig. 6 shows a section of a shingle made according to this invention.

`In the drawings, the ordinal 6 indicates a reservoir containing the coating material arranged to feed this material 7 onto the felt base 8 of the shingles as it passes over a table 9 from` a roll 10. This roller l() is provided under the felt and adjacent to the table 9 to 4cause the felt to move along. knife 11 is provided over the roll 10 and near the point where the coating is fed guides in place. plan view of the guides in place.

Y t0 the felt for thepurpose of spreading uniformly the coating upon the felt. This knife 11 is adjustable as to its angle of slant upon its pivot 12 to vary the thickness of theJ coating compound upon the felt. We may modify this however, and use a roller 12 to regulate the thickness of the coating as shown in Fig. la. A hopper 13 is provided to feed sand or grit while the coating composition is still wet to which it sticks.

l Now in order to limit the coating composition to only that portion of the felt base that it is desired to cover, adjustable guides 14 are provided in `front of the knife 1l and so arranged over the felt base that they will prevent the plastic coating composition from covering any other portion of the felt except that between the guides as shown in Fig. 3. The sand or grit may be fed to the entire felt base as it will only stick to that portion whereon is the adhesive coating. The finished product of the arrangement shown in Fig. 3, appears as Fig. 4 which consists of alternate strip of uncovered felt and felt covered with the coating and sand. This is then cut in two to form two strips of material from which shingles of the new construction are cut.

The special roofing shown in Fig. 5 is made up of material as above described but is wider than the ordinary shingle material and in this case it is only desirable to have a space of two inches at one side remain uncoated. This is accomplished in our device by only using one of the guides 14 to confine the coating material to within the two inches of one edge it is desired to leave uncovered. However, we do not wish to conne ourselves to the products as shown in Figs. 4 and 5, as we may produce any article consistent with the spirit of this invention, such for instance, as a shingle shown in Fig. 46. j

We claim as our invention 1. As a new article of manufacture a composition roofing material adapted to be cut into shingles, comprising a single ply fabric having applied thereon a plurality of protecting layers of adhesive and sand in continuous strips with alternate parallel strips of the exposed felt surface lying between said coated portions, and of substantially the same width so that when cut along the line of two adjoining strips to form shingle stock`having one end formed of single layer and the other end, which is to be single ply and being uncoated, said coated exposed to the Weather, formed with a plurality of protecting layers.

As a new article of manufacture, composition roofing material adapted to be used as roong or shingle stock comprising a single ply fabric having a plurality of continuous strips of layers of adhesive and sand applied to its surface, adapted to be eX- posed to the Weather, the remaining portion yforming an underlap `being formedl of the and uncoated strips being of substantially equal areas, substantially as described.

In testimony whereof, We aHiX our signa- 15 tures in presence 'of two Witnesses.
